Cap polyposis is characterized by the presence of inflammatory polyps with a "cap" of granulation tissue. It may represent one end of a spectrum of conditions caused by chronic straining.

 Cap polyposis is characterized by the presence of
 inflammatory polyps with a "cap" of granulation tissue. It
 may represent one end of a spectrum of conditions caused
 by chronic straining.
 Polyps have an erythematous and inflamed appearance
 and are capped with a purulent fibrin exudate.
 The pathogenesis is not well known although many
 affected individuals have long standing colonic dysmotility
 manifested by chronic constipation. It is hypothesized that
 recurrent mucosal trauma due to chronic straining can
 result in the clinical spectrum of mucosal prolapse
 syndrome which includes solitary rectal ulcer syndrome
 and the more dramatic finding of cap polyposis.
 
The findings here are of cap polyposis, a rare condition thought to be related to chronic constipation and straining causing prolapse of mucosa in the rectum and sigmoid. Often mistaken for pseudopolyps, the polyps seen can range from sessile to pedunculated in morphology and can be found anywhere from the rectum to the cecum although the vast majority are found in the rectosigmoid region as in this example.

Chromoendoscopy with indigo carmin. Cap polyposis is characterized by rectosigmoid polyps that have tortuous elongated crypts and are covered by a cap of fibropurulent exudate. The pathogenesis is unknown, but the histology suggests that mucosal prolapse may play a role. The current therapy often used for inflammatory bowel diseases has frequently been ineffective. Overall, infliximab lead to symptomatic improvement and histologic resolution of the polyps
